Add check for php.ini in same directory as php.exe (or equivalent executable that loaded php4ts.dll). Check is done before looking in the Windows directory. This allows distinct php.ini files when different applications using PHP are installed on the same system. Should be backwards compatible.
Note that checking for in CWD php.ini may be a security risk(?), and can now be made compile-time configurable by removing a single #define. (This time with tabs for leading indent).
